KANDUNGAN PIPERIN DALAM EKSTRAK BUAH LADA HITAM DAN BUAH LADA PUTIH (Piper nigrum L.) YANG DIEKSTRAKSI DENGAN VARIASI KONSENTRASI ETANOL MENGGUNAKAN METODE KLT-DENSITOMETRI

Abstract

Kualitas ekstrak buah lada ( Piper nigrum L.) dipengaruhi oleh komponen dan kadar senyawa didalamnya. Piperin merupakan senyawa alkaloid utama dalam buah lada. Banyaknya piperin yang larut selama proses ekstraksi dipengaruhi oleh jenis pelarut yang digunakan. Penelitian ini didesain untuk mengetahui kadar piperin dalam ekstrak buah lada hitam dan lada putih yang diekstraksi dengan variasi konsentrasi etanol. Ekstraksi buah lada dilakukan dengan metode ekstraksi sokhlet menggunakan variasi konsentrasi etanol (60%, 70% dan 96%) dan kemudian dilanjutkan dengan teknik ekstraksi asam-basa untuk mendapatkan ekstrak alkaloidnya. Ekstrak alkaloid masing-masing dianalisis pada plat KLT silika gel 60 F 254 sebagai fase diam dan campuran n -heksana:etil asetat (1:1) sebagai fase gerak. Kadar piperin ditetapkan menggunakan metode KLT-densitometri pada panjang gelombang 254 nm. Hasil menunjukkan bahwa kadar piperin tertinggi diperoleh dari ekstrak buah lada hitam menggunakan pelarut etanol 60% sebagai pelarut pengekstraksi dengan kadar 52,81±4,66 (%b/v) terhadap ekstrak alkaloidnya. Kadar piperin tertinggi diperoleh dari ekstrak buah lada putih menggunakan pelarut etanol dengan konsentrasi 96% sebagai pelarut pengekstraksi dengan kadar 38,72±8,28 (%b/v) terhadap ekstrak alkaloidnya.
